Using C#: Briefly explain how to create instance variables, and show how to define a private integer instance variable called idNumber within a class called Employee.
Homework Answers
Creating instance variable in C# is same as java.
We usually create private type of variables in java in order to provide hidden implementation. This implementation is called Encapsulation .
the below line is a directive which is used to initialize the system pre-defined methods and variables related to C#
Using system;
//our class Employee starts here
class Employee {
//declaring a private instance variable here
private int idNumber;
}

In one file create an Employee class as per the following specifications: three private instance variables: name (String), startingSalary (int), yearlyIncrement (int) a single constructor with three arguments: the name, the starting salary, and the yearly increment. In the constructor, initialize the instance variables with the provided values. get and set methods for each of the instance variables. A computation method, computeCurrentSalary, that takes the number of years in service as its argument. The method returns the current salary using...

Create a class Circle with one instance variable of type double called radius. Then define an appropriate constructor that takes an initial value for the radius, get and set methods for the radius, and methods getArea and getPerimeter. Create a class RightTriangle with three instance variables of type double called base, height, and hypotenuse. Then define an appropriate constructor that takes initial values for the base and height and calculates the hypotenuse, a single set method which takes new values...

Write a class called Pen that contains the following information: 1. Private instance variables for the price of the pen (float) and color of the pen (String). 2. A two-argument constructor to set each of the instance variables above. If the price is negative, throw an IllegalArgumentException stating the argument that is not correct. 3. Get and Set methods for each instance variable with the same error detection as the constructor. public class Pen {

Explain how class (static) variables and methods differ from their instance counterparts. Give an example of a class that contains at least one class variable and at least one class method. Explain why using a class variable and method rather than an instance variable and method would be the correct choice in the example you select.
